Key Features
- 36-position dual-row (18x2) socket at 0.050" (1.27 mm) pitch in tape-and-reel packaging for high-volume automated PCB assembly
- High-reliability gold-plated contacts deliver low contact resistance and long mating cycle life for demanding interconnect environments
- Surface mount termination enables single-pass SMT reflow assembly, reducing manufacturing complexity versus through-hole alternatives
Applications
The SFM-118-T2-ZZ-D-A-K-TR suits high-density module-to-motherboard interfaces in networking switches, embedded computing platforms, and industrial control systems requiring 36 signal channels within a compact 0.050" pitch SMT footprint. The tape-and-reel packaging option makes it production-friendly for high-volume automated assembly lines in consumer electronics and telecommunications equipment. Its dual-row surface mount design also supports FPGA daughter-card and expansion module connections where board real estate and signal channel count must both be optimized.

Frequently Asked Questions
What pitch and pin count does SFM-118-T2-ZZ-D-A-K-TR provide, and how does the tape-and-reel suffix benefit production runs?
SFM-118-T2-ZZ-D-A-K-TR provides 36 positions in a dual-row (18x2) layout at a 0.050" (1.27 mm) pitch. The -TR suffix denotes tape-and-reel packaging, which feeds directly into standard pick-and-place machines, supporting automated assembly at production rates that are impractical with cut-tape or tray-packaged alternatives, and reducing per-unit placement cost in high-volume runs.
How does the 36-position SFM-118 compare to the 44-position SFM-122 when designing a compact expansion interface?
Compared to the 44-position SFM-122, the 36-position SFM-118-T2-ZZ-D-A-K-TR has an 18x2 dual-row layout at the same 0.050" pitch, resulting in a shorter PCB footprint with 8 fewer signal channels. Designers choose SFM-118 when the interface specification requires exactly 36 channels, avoiding unused pins and saving approximately 4 mm of connector length on the PCB compared to the 22x2 SFM-122.
Which PCB soldering process is compatible with SFM-118-T2-ZZ-D-A-K-TR, and at what typical peak temperature?
SFM-118-T2-ZZ-D-A-K-TR uses surface mount termination compatible with standard SMT reflow soldering at peak temperatures of 245°C to 260°C per JEDEC J-STD-020. The connector processes alongside other SMT components in a single reflow pass, covering all 36 contact positions without wave soldering or hand soldering, which simplifies the manufacturing process and reduces defect risk.
In what applications does the high-reliability rating of SFM-118-T2-ZZ-D-A-K-TR justify its use over a standard socket strip?
High-reliability rated socket strips like SFM-118-T2-ZZ-D-A-K-TR are preferred in industrial automation controllers, mil-grade embedded systems, and telecom line cards where contact failure across 36 pins would cause costly system downtime. The enhanced gold plating and contact spring geometry maintain stable electrical performance over thousands of mating cycles and across operating temperatures from -55°C to +125°C, exceeding the performance of standard commercial socket strips.
